7 Claims.

This invention relates to a well-known type of mantle steaming machineand the principal objects of the invention are to provide simple andeffective means for securing suitable tension upon the mantle while itis being wound onthe steaming cylinder; to provide means for indicatingthe amount of tension and particularly for indicating when it varies dueto wear or misadjustment; to provide extremely simple means whereby theoriginal tension can. be restored in case of fiuc tuation and to provideeffective means for shifting the power from the steaming cylinder to themantle roll and vice-versa and preventing both of them being connectedwith the power at the 16 same time.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which 1 20 Fig.1 is aside view of the principal part of a mantle steaming machineconstructed in accordance with this invention and showing the mantlbeing wound on the mantle roll;

This invention is shown as applied to a machine for processing cloth,commonly known as a mantle steaming machine. As shown in the drawings,the machine involves certainfeatures which are well known. It has apower shaft 10 which by means of sprockets 11 and 12, respectively, andchains thereon is adapted to transmit power to a steaming cylinder 13and to a mantle roll 14. ,Thisis done by means of sprockets 0n theshafts of these two rotary members. The steaming cylinder 13 isperforated, as usual and the cloth 15 to be processed is brought underand over guides and over an idle roll 16 to the steaming cylinder andwound thereon with the mantle 17 which is unwound from the mantle rolland wound on the steaming cylinder around the roll 16in alternate layerswith the fabric to be treated.

The steaming cylinder, as has been the case heretofore, is drivenforward to wind up the mantle and fabric thereon and, as stated, thesteaming cylinder is perforated to permitof the exhausting of the steamfrom the same through the cylinder itself. The mantle will be rolled upthen on the mantle roll and drawn from the steaming cylinder, takingthecloth off the steaming cylinder with it and delivering the cloth fromthe machine. Suitable devices are provided for guiding the cloth andmantle. All this as sofar described is old and well known. 1

. It is also old to provide means for tensioning the mantle as it passesthrough the steaming cylinder from the mantle roll but one of theobjects of this invention is to provide an improved tension device forthis purpose combined with meansf or releasing it upon reversal andallowing free rotating during reversal. V

The driving shaft 10, of course, rotates in a forward direction all thetime and the sprockets 11 and 12 are provided with clutches l9 and 20,by which vthey can be connected with the driving shaft or freed from it.These clutches are operated by two levers 21 and 22 respectively,pivoted at 23 on the same shaft and connected with their respectiveclutches by yokes having pivot pins 24 and 25. These two levers 21 and22 can be operated independently except for the fact that one of them isprovided with an arcuate slot 26 and the other with a pin 2'? enteringthe slot. This allows freedom of motion of each lever for a certaindistance and then compels the other lever to follow it.

In the position shown in Fig. 2 the lever 22 has just been pulled overfrom the right to the position shown and the pin 27 has caused the lever21 to be pulled over also to the position shown. This connects theclutch and disconnects the clutch 19. Pulling the lever 21 to the right,as indicated by the arrow, will have the opposite effect or bring themboth to neutral position and then connecting the clutch 19 anddisconnecting the clutch 20. Therefore the steaming cylinder and themantle roll cannot be connected with the power at the same time.

The shaft 30 of the mantle roll is shown as provided with a brake drum31. This drum is not fixed to the shaft but is concentric therewith. Onthe shaft is shown a cam 32 illustrated as consisting of four camsurfaces. Fixed to the brake drum 31 is an outer cam 33 also consistingof four cam surfaces. Between each cam surface 32 and the correspondingcam surface 33 is a roller 34 resting between them. During theunwinding, which is indicated by the arrow and by the position of therollers or balls in Fig. 5, each roller is jammed against thecorresponding internal curved cam surface 33.

By such contact is produced a forward driving connection which willrotate the drum from the shaft. The reversing of the rotation of theshaft, however, immediately and automatically disengages all or saidrollers and allows them to roll up into the high part of their camsurfaces. An entire freedom of rotation in the mantle winding directionis secured. This is important be cause during the forward rotation, whenthe mantle is being wound on the steaming cylinder, it is essential thattension be applied to the mantle to keep it winding the cloth alwayswith'the same degree of tightness on the steaming cylinder. This can bedone by the application of a brake to this drum 31. It is also essentialthat when the mantle is being unwound from the steaming cylinder no suchtension should be applied and consequently when the shaft 30 is beingrotated from the shaft 10 to draw the mantle from the steaming cylinder,complete freedom of braking of the mantle roll is accomplished. Theseobjects are secured by this arrangement.

The application of a brake to the drum 31 has been mentioned. This canbe accomplished by the provision of two pivoted brake supports 37 havingbrake surfaces 38 operating directly on the outside surfaces of the drum31 which is cylindrical. A rod 39 is fixed to one of these supports 37and extends through the other. It is screw-threaded and has a hand nut40 adjustable along the screw-threads. A spring 41 is provided to helphold the two supports apart and a spring 42 to produce pressure on thesupport, the spring 41 having lower compression than the spring 42.

The nut is provided with a scale 43 and the support 37 is provided witha pointer 44. The object of this construction is to provide for set-,ting the nut at first so as to get what is decided to be the exactamount of tension for the kind of cloth being processed. Now theposition of the pointer on the scale is noted.

In the use of the device the tension may be reduced by wear or accidentand, if so, this will show up immediately on the scale. Then the nut maybe turned as much as may be necessary to bring it back to the properposition with respect to the pointer, which will give the same tensionas that at the start of the operation.

The brake is always applied to the drum 31. This drum is loose on theshaft 30 when that shaft is connected to be driven by the shaft 10 andtight when the shaft 46 is being driven by the shaft 10 by the action ofthe parts 32, 33 and 34.

Although this release and brake has been de scribed in connection onlywith the shaft 30 of ,after being processed is driven from the 'mainshaft, or other source of power, through a friction clutch. This driveis disconnected when the processing is being done and the mantle rollrotates in the opposite direction by the rotation of the steamingcylinder winding the mantle upon itself. It is during the winding of themantle on the steaming cylinder that a suitable tenmatter to turn up thenut and bring the indiupon it from the mantle roll, means fordisengagsion is desired and no tension practically when the mantle isbeing wound up on the mantle roll. The drum is released automaticallyand stopped when the reversal of the roll is made and this is donewithout affecting the setting of the braking system so that noadjustments have to be made between the alternate rotations of themantle roll in opposite directions.

It will be seen also that, by the indicator mentioned, the operator canadjust the tension to a proper amount and without any furthermanipulation on his part the degree of tension will be indicated.Thereafter if there is any variation in the tension due to wear oraccident or the like, the indicator will show it and it is a very simplecator back to it's original position which the operator knows willprovide the original amount of friction. In this way the tension can bekept constant after once being adjusted to be suitable for theparticular kind of fabric being run.
